This subject keeps cropping up. Is this a serious issue ? I have heard that IMD improves by 10db with a one volt increase in supply voltage. Is this really the case or just a measurement error? 10db is a large difference. One volt is a small variation.
What is the minimum acceptable IMD? How linear does the amp need to be? If 36db is better than 26db is 100db even better or just overkill? Are other solid state amplifier products similarly effected? What is the IMD performance of the K3S at 10 watts over a supply voltage variation from 11 volts to 14.7 volts? I ask because I believe those ten watts are generated by Dmos devices as well. Do these devices only misbehave with varying supply voltage at higher (100w) power levels and lower supply voltages? Should I wait to purchase a K3S until this issue is resolved? (Assuming this is a valid issue) Back in the good old days we used to solve problems. Today we don't have problems, just issues. -- Frank - K5DKZ KX3 - 7550 PX3 - 1143 KXPA100 - 1566 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
